# Utilizing aLIGO glitch classifications to validate gravitational-wave candidates

@article{Davis2020UtilizingAG, title={Utilizing aLIGO glitch classifications to validate gravitational-wave candidates}, author={Derek Davis and L. V. White and Peter Saulson}, journal={Classical and Quantum Gravity}, year={2020}, volume={37} }

Advanced LIGO data contains numerous noise transients, or ‘glitches’, that have been shown to reduce the sensitivity of matched filter searches for gravitational waves from compact binaries. These glitches increase the rate at which random coincidences occur, which reduces the significance of identified gravitational-wave events. The presence of these transients has precipitated extensive work to establish that observed gravitational wave events are astrophysical in nature. We discuss the…
